Yes, this is the very essence of a trial version, which is to work with all features enabled for prospective users to try the full software for a certain time. The trial time for FPV Pro lasts a couple of weeks, which should be enough for anyone to try out the main features, see how well the software works for them and how it can help their workflow.

You are welcome to acquire an FPV Pro license from our web page at http://www.fastpictureviewer.com/buy/, we'll provide you with a license key that re-enables all functions immediately, starting with full RAW support.

After the trial expires the prorgam is limited to JPEG and HD Photo viewing, and some of the advanced features are disabled (like XMP rating or batch file processing).
